Determination of interface cohesive zone parameters of a mixed mode cohesive law by in-situ delamination experiments

Cohesive zone (CZ) approach is often used to describe the interface behavior in finite element (FE) predictive models to minimize delamination failures (Fig. 2). Experimental determination of all the interface CZ parameters of a mixed mode cohesive law is an ongoing challenge.

Goal:
Present an approach for determination of mixed mode interface
CZ parameters
